I'm never so sure about using the right words. But if totem pole, then two
totem poles (for the two clock inputs). Now in switched power supplies,
you use two totem poles (=  one H bridge) to drive a floating winding
indeed.
So even if in the BBD application you wouldn't call it H-bridge, you might
call it H-bridge in a switcher IC that you want to (ab)use as BBD driver.
